Steps:

* Generate initial sphinx project:

```
$ mkdir docs & cd docs
$ sphinx-quickstart
```

* Add `requirements.txt`

```
$ echo "furo
myst-parser[linkify]
sphinx
sphinx-design" > requirements.txt
```

* Edit `conf.py`
  - replacing single quotes with double quotes
  - setting these variables:
    - `extensions`
    - `myst_enable_extensions`
    - `myst_heading_anchors`
    - `html_theme` (change theme to "furo")

* Delete `index.rst`

* Add `README.md` and `overview.md` (itself including `README.md`)
